The TPS92544-Q1 device contains a synchronous BOOST controller and a monolithic synchronous buck LED driver with a wide 4.5V to 65V operating BUCK input voltage range.

The synchronous BOOST controller implements a peak current-mode controller to operate in constant voltage mode. The output voltage can be programmed using a programmable 8-bit DAC.

The monolithic synchronous BUCK implements an adaptive on-time average current mode control and is designed to generate constant voltage (CV) or constant current (CC) output. In the CC mode, the BUCK is compatible with shunt FET dimming techniques and LED matrix manager-based dynamic beam headlamps. In CV mode, the adaptive on-time control enables high bandwidth operation with fast transient response. The adaptive on-time control provides near constant switching frequency that can be set between 100kHz and 1.0MHz. Inductor current sensing and closed-loop feedback enable better than ±4% accuracy over wide input voltage, output voltage and ambient temperature range. In CC mode, the BUCK can independently modulate LED current using both analog or PWM dimming techniques.

The TPS92544-Q1 includes an internal oscillator. The UART serial interface is compatible with TPS9266x, and TPS9254x devices. The internal EEPROM can store system defaults as well as calibration and lighting module data. The seven configurable MPIOs and DIOs can be set as digital inputs or outputs, or ADC inputs for applications with system temperature compensation, LED binning and coding, etc.

The TPS92544-Q1 is available in a 7.0mm × 7.0mm thermally-enhanced 48-pin HTQFP package.
